Ten musicians (above) each chose a commercial recording that they thought could benefit from something being added to it. Each musician received all 10 tracks and each added something to all of them. Nobody heard anything but the original pieces, so no one knew what anyone else had added. Jocelyn Robert gathered all the recordings together, lined up the 10 added tracks from each - still synched to the original commercial recording - erased the originals and mixed the remaining overdubbed parts into a self-standing piece. Each piece, therefore, owed its existence to a commercial recording, but nothing of that recording remained. The result is this CD - which was commissioned to accompany a conference on copyright in Quebec. It's complicated, rich - and experimental - since there is always the phantom of the erased structure holding everything together. Not everything works, but.. In common with many recent releases, there is a minimum of information on the digipack, just a list of names - see above - but no indication of what each of them played, plus a list of the original tracks erased. A fascinating project, nicely realised, by a pretty good band.
